Duet has raised a $15 million Series A to expand support for nurse practitioner-owned primary care clinics as it prepares a Medicare accountable care organization, or ACO, for 2027, Fierce Healthcare reported on November 12. Kairos led the round, with Lerer Hippeau participating.
Medicare generally sets allowed fees for nurse practitioners at 85% of the physician fee schedule. Duet’s planned ACO would give practices a route to additional payments: participating providers can share savings when Medicare spending stays below benchmarks and care meets quality standards.
Duet supports the business side of primary care, with billing, coding, scheduling and insurer-enrollment services. Its published service model includes a practice adviser, while its patient-engagement tools automate outreach to bring patients back for appointments.
The company says nurse practitioners would govern its ACO and retain control of their practices and treatment decisions. Its general service terms leave clinical authority and ownership of medical records with the practices, and say Duet does not hire or supervise their clinicians.
Executives told Fierce that Duet works with more than 130 clinics across 21 states. Founder and CEO Jonathan Goldberg said the capital would support additional clinic partnerships, insurer contracts tied to care results and engineering hires. He also described an accelerator program for new clinics planned for 2027.
